OK ....Gary it was a joke just meant to say they were harder to open than a normal clamp... you need to relax maybe have a beer and chill out on that land of yours.
Great article... I have used these principals before and never realized why lol when you learn you grow!
I am a big guy 6 ft 205 pounds and I workout regularly but trying to open some of those cheap A clamps are frustratingly hard,by the time your done with them your sweating like a gypsy with a mortgage.
Its a struggle to find grants for Caribbean filmmakers like myself....another long list that we cannot really benefit from ....sigh... (i'm especially talking about the narrative short category)
